Lera returns to her hometown for her grandmother's funeral. The communal apartment, where she spent her childhood vacations, greets her with creaks, rustles, and persistent stomping from above… although no one has lived upstairs for a long time. Among her grandmother's belongings, Lera finds a pendant with a warning: "Do not wear".
Trying to make sense of the horrific urban legends and her own feelings, Lera realizes: her grandmother was hiding something far more terrifying than the crumbling walls of the house. With each passing day, Lera delves deeper into the atmosphere of the mysterious mansion, where the past comes alive, secrets multiply, and logic is powerless.
